In an apparent microcosm of their season to date, The Gunners came under severe pressure for much of the first half on Tuesday evening and had to cope with injuries – this time to William Gallas and Manuel Almunia – before clawing their way back into the tie thanks to Emmanuel Adebayor’s sumptuous goal.

That away goal leaves Wenger’s side in pole position to progress to the last four and Wenger is confident that his fledglings’ increased stature can see them through.

"It puts us in a great position, but we want to qualify at home and to repeat the type of performance we did in the second half," he said.

"I am confident, the quality we have shown added to the mental strength and desire we have shown.

"But we know Villarreal are a good team as well, so we will be on our toes and focused at Emirates.

“This team has shown the whole season they are mentally very strong and when they have back to the wall, these young players always find an answer which is very interesting for a young team.

"I believe we have created momentum. We are a very young team, but are capable to focus.

"We have shown with the consistency we have in the championship that we are able to concentrate every three days, and at that age, that is a big quality."
